[Dovecot] messages_count too large errors (1.0RC5)
by Jeff Turner 22 Aug '06

22 Aug '06

Hi, Just today, Thunderbird started throwing errors when accessing a particular mail folder. Looking in the logs showed this: dovecot: Aug 09 15:36:31 Error: IMAP(nmenere): Corrupted index file /imap/mailboxes/nmenere/shared-settings/jira-support/index/.INBOX.Triaged/dovecot.index: messages_count too large (51 > 39) This is a new user's first attempt to access a shared jira-support/ folder, so there is no chance of their index files being corrupt. Deleting the dovecot* files didn't help. Neither did 'cp -rp .INBOX.Triaged .INBOX._Triaged' and then subscribing to the new folder. In fact, the problem seems to be with the files in cur/. There are 51 in total, and 39 of them have an 'i' flag: 1155084961.P27685Q5.redback.sydney.atlassian.com:2,Sbrk 1155084979.P27685Q6.redback.sydney.atlassian.com:2,Sbtk 1155085103.P27685Q10.redback.sydney.atlassian.com:2,Sbwk 1155085175.P28321Q1.redback.sydney.atlassian.com:2,Sbcki 1155085221.P27685Q12.redback.sydney.atlassian.com:2,Sbwk 1155085228.P28321Q4.redback.sydney.atlassian.com:2,Sbki 1155085231.P28321Q5.redback.sydney.atlassian.com:2,Sbki 1155085246.P28321Q6.redback.sydney.atlassian.com:2,Sbki Loading the maildir in mutt and re-saving them all to a clean maildir fixes the problem, by resetting the flags. Going through the logs, I see other users hitting this problem with other mailboxes. Anyone know what 'i' means? I guess it's a dovecot extension? I should mention that this happened a few months ago too, with 1.0b8 (I think). This is all running on a linux box, mail delivered with procmail, no special settings. Anyone seen this before? Cheers, Jeff

[Dovecot] Dovecot authorisation problem
by Phil Clare 21 Aug '06

21 Aug '06

Hi List, I am trying to set up dovecot on my mail server and am having some difficulties… I want to use virtual mailboxes and so have set up a passwd-file for userdb and passdb and created entries for a user but they don’t seem to be working… I have included the relevant lines from all three files below… Dovecot.conf… auth_userdb = passwd-file /etc/dovecot/users auth_passdb = passwd-file /etc/dovecot/passwd users file… HYPERLINK "mailto:phil@topazaccommodation.co.uk::503:503::/var/mail/vhosts/topazaccomm odation.co.uk:/bin/false"phil@topazaccommodation.co.uk::503:503::/var/mail/v hosts/topazaccommodation.co.uk:/bin/false:: passwd file… phil@topazaccommocation.co.uk:$1$G/FqlOG5$Vj0xmc9fKY.UVr8OWr/7C1 As far as I know the password is the word ‘test’ encrypted with MD5 (is there anyway to have these as plain text?) Finally the entry from the log file… Aug 18 16:51:58 95304-web1 dovecot-auth: passwd-file(phil(a)topazaccommodation.co.uk): unknown user Any ideas?

[Dovecot] dovecot vs qpopper performance testing results
by asko 21 Aug '06

21 Aug '06

Hi, I did some performance testing with dovecot and qpopper, if anyone is interested.. Hardware: Dual Xeon 2.8 with HT enabled (dmesg sees 4 cpu-s), 1 GB RAM, SCSI RAID 1 with 2x Maxtor Atlas 10K V disks. Software: CentOS 4.3, Qpopper 4.08 in standalone mode vs Dovecot 1.0-0_19.rc6, ext3 filesystem Mailbox format Mbox, tested Pop3 with PAM authentication My setup had 15 test users with 15 identical 40 MB mbox files. Each mbox had 370 messages, 35 % of them had attachments. So average message size is about 110 KB, average attachment size 220 KB. "rabid" utility is part of postal package (http://www.coker.com.au/postal/) Command line, which fetches and deletes all the messages from users in the textfile: rabid -p 1 192.168.x.x ./users - Resulting fields are: time,messages,data(K),errors,connections,SSL connections,IMAP connections Results (only the best one shown): Qpopper: 1 parallel processes: 12:36,1020,111470,0,6,0,0 5 parallel clients: 12:44,3246,366207,0,13,0,0 15 parallel clients: 13:06,4099,481347,0,48,0,0 Dovecot: p1: 12:19,3316,367859,0,13,0,0 p5: 12:50,4653,524456,0,34,0,0 p15: 12:56,5063,578889,0,84,0,0 As you can see, Dovecot is faster.. With 15 parallel processes it seems to have saturated my 100Mbit/s LAN (578889 kB data in one minute). Dovecot had noticeably smaller disk IO and system load was smaller too, probably thanks to smaller IO. Qpopper performed better than I hoped.. It is probably due fast disks of the test system, I wouldn't expect such numbers using single IDE disk. Conclusion: The hardware was too fast for testing, LAN became a bottleneck atleast once. The results could be different with different mbox structure.. Anyway, I was convinced, Dovecot wins. -- asko

Thanks, thanks, thanks! This, apparently, was the problem, and, once I figure out where to find the pkg-config source (not bundled with OSX?), following your instructions cleared it up. Again.

[Dovecot] Acl, Namespace, User Confusion
by Jim Horner 19 Aug '06

I'm using dovecot RC6. I have a group named "cmpymail" with 2 users "jdoe(a)arinbe.com" and "jsmith(a)arinbe.com". I set up a mail folders like: drwxrwx--- 4 cmpymail cmpymail 4096 2006-08-13 02:21 cmpymail drwxrwx--- 3 jdoe users 4096 2005-11-21 13:34 jdoe drwxrwx--- 3 jsmith users 4096 2006-08-13 02:27 jsmith drwxrwx--- 3 fred users 4096 2006-08-13 02:27 fred drwxrwx--- 3 wilma users 4096 2006-08-13 02:27 wilma In dovecot.conf namespace public { separator = . prefix = COMPANY. location = maildir:/home/services/mail/arinbe.com/company/Maildir:CONTROL=%h/shared-se… hidden = no } I have a dovecot-shared file -rw-rw---- 1 cmpymail cmpymail 0 2006-08-13 13:24 dovecot-shared What I can not do is restrict access to cmpymail to -just- jdoe and jsmith. I've looked at http://www.dovecot.org/list/dovecot/2006-June/013683.html I've tried adding mail_plugin_dir = /usr/local/lib/dovecot/imap mail_plugins = acl and a dovecot-acl file owner user=jdoe(a)arinbe.com lrwstiekxa user=jsmith(a)arinbe.com lrwstiekxa user=jdoe rwstiekxa user=jsmith lrwstiekxa I am not exactly sure what username to use. All users are in LDAP. The "cmpymail" group shows # getent group cmpymail:*:5555:jdoe,jsmith Nothing I do seems to work. I either get errors that wilma and fred can't access cmpymail, for instance when wilma/fred try to subscribe to folders, or wilma and fred have complete access to cmpymail (if I change cmpymail's group to users instead of cmpymail). Is there a way to restrict access like I want? Thanks, Jim

Dear Tim Schafer, Take a look at my sample dovecot-ldap.conf hosts = localhost dn = cn=root,dc=ceylonlinux,dc=com dnpass = secret ldap_version = 3 base = dc=ceylonlinux,dc=com deref = never scope = subtree user_attrs = mail,homeDirectory=mailMessageStore,uidNumber=1003,gidNumber=1003 user_filter = (&(objectClass=user)(mail=%u)) pass_attrs = mail=user,userPassword=password pass_filter = (&(objectClass=user)(mail=%u)) default_pass_scheme = CRYPT user_global_uid = 1003 user_global_gid = 1003 Here I am using my own schema called "user", but in your case change it to inetOrgPerson or the schema name you are using. I think the most common problem in this process is the ldap filter. Above in my configuration user_filter and pass_filter are used as ldap filters for querying user name and password. There I am using mail attribute. gid and uid are belong to the user vmail. May be this explanation will help you to figure out your problem You can refer my article in the following link for further reference http://www.ceylonlinux.com/pdf/openldap_backsql_postfix_maildir_cl.pdf Cheers!!!
